did humans evolve in fits and starts?

Associate Professor Evan Eichler at the University of Washington in Seattle thinks so.
Humans may have evolved during a few rapid bursts of genetic change, according to a new study of the human genome, which challenges the popular theory that evolution is a gradual process.

Researchers studying human chromosome 2 have discovered that the bulk of its DNA changes occurred in a relatively short period of time and, since then, only minor alterations have occurred.

This backs a theory called “punctuated equilibrium” which suggests that evolution actually occurred as a series of jumps with long static periods between them.
